Description

Technical Field

[0001] This invention relates to the field of electricity meter technology, and more particularly to an electricity meter with a built-in switch. Background Technology

[0002] A switch-embedded energy meter is an electrical metering device used to measure, monitor, and record the electrical energy consumption in a circuit. It monitors the current by configuring a current sensor inside the energy meter.

[0003] A search revealed a Chinese invention patent, publication number CN119125636A, entitled "A Switch-Built-In Electricity Meter." This invention uses a ring-shaped airbag to seal the gap and hinge between the meter cover and the meter body, while simultaneously limiting the position of the meter cover and the meter body to prevent external moisture from entering the meter body. When the meter cover is opened, it is automatically limited when fully opened to prevent the meter cover from interfering with the operator's inspection of the meter body. At the same time, the ring-shaped airbag and the U-shaped airbag contract to prevent the inflated ring-shaped airbag and the U-shaped airbag from obstructing the operator's view of the inside of the electricity meter body.

[0004] However, in actual use, the above and similar technical solutions still have some problems: 1. The current sensor adopts a built-in design and does not synchronously detect the input and output currents. This makes it difficult to achieve precise power control. During power operation, it is difficult to grasp the current dynamics in real time and accurately, and thus it is impossible to detect abnormalities such as electricity theft, insulation faults, leakage, and meter failures in a timely manner, which affects the safe and stable operation and efficient management of the power system. 2. The equipment relies solely on a built-in switch to achieve power-off functionality, which is a single power-off method. In the event of a short circuit, if the built-in switch fails to cut off the circuit in time, it is very easy to cause a serious accident. At the same time, the equipment lacks manual power-off functionality and other diverse power-off methods. Furthermore, there is no corresponding power-off protection mechanism when faced with forced disassembly, resulting in significant safety loopholes. 3. The equipment uses a method of directly connecting the wires to the terminals. This wiring structure lacks an effective protection mechanism. In actual use, if the wires are dragged, they can easily detach from the terminals. The fallen wires will not only damage the normal connection of the circuit, but may also cause serious injuries such as electric shock to people in the vicinity, posing a great safety hazard to the use environment.

A trigger component 54 for pushing the slider 55 is connected to the energy meter body 1, thereby facilitating the switching of the circuit by controlling the sliding of the slider 55.

[0024] In this invention, the triggering component 54 includes a push block 543, which is slidably connected to the main body 1 of the energy meter.

The solenoid valve 542 is electrically connected to the main body 1 of the electricity meter. In the event of a short circuit, the main body 1 of the electricity meter controls the solenoid valve 542 to open, expelling the gas inside the second airbag 545, releasing the limit on the push block 543, and also achieving power cut-off. After maintenance, the cover plate 31 is opened. At this time, the fourth spring 548 extends, the first airbag 544 expands, external gas is drawn into the first airbag 544, the solenoid valve 542 is closed, and it can be used again.

[0026] In this invention, a locking mechanism 7 is connected to the main body 1 of the electricity meter.

A slot 73 is provided on one side of the push block 543. The lock tongue 72 is driven into the slot 73 by the lock cylinder 71. When maintenance personnel are performing maintenance, they drive the lock tongue 72 into the slot 73, thereby limiting the push block 543. When the cover plate 31 is opened again, the slider 55 will no longer slide, thus eliminating the need to prevent the circuit from being disconnected.

[0027] In this invention, the end of the wire 2 is inserted into the first terminal 56. A bolt 53 is threadedly connected to the fixing block 52. The threaded end of the bolt 53 moves through the outer wall of the first terminal 56.

The plug rod 33 extends into the socket 34 and is plugged into the main body 1 of the electricity meter, thereby facilitating the plugging of the cover plate 31.

[0029] In this invention, a limiting component 32 is connected to the main body 1 of the electricity meter. The limiting component 32 includes a limiting block 321. The limiting block 321 is slidably connected to the main body 1 of the electricity meter. A first spring 323 is installed between the limiting block 321 and the main body 1 of the electricity meter. A limiting groove 322 is provided on the main body 1 of the electricity meter. The limiting block 321 extends into the limiting groove 322 through the first spring 323, thereby facilitating the limiting of the cover plate 31.

[0030] Example 2: Based on Example 1, a switch with an internal energy meter is provided. A sensing mechanism 6 is connected to a slider 55. The sensing mechanism 6 includes a current sensor 62. The current sensor 62 uses a non-contact inductor coil for detection. The current sensor 62 is installed on the slider 55 and is sleeved on the outer wall of the conductive cylinder 59. The current sensor 62 is electrically connected to the energy meter body 1 by a connecting wire 61, thereby detecting the input and output current and realizing precise control of the circuit.

[0031] Example 3: Based on Example 2, a switch with a built-in electricity meter is provided. The electricity meter body 1 is connected to a protective mechanism 4. The protective mechanism 4 includes a plug 41. The electricity meter body 1 is plugged into each fixed block 52 with a plug 41. The wire 2 passes through the plug 41. A rubber telescopic tube 46 is fixedly connected to the end of the wire 2 at the plug 41. This protects the end of the wire 2 after it is detached. The rubber telescopic tube 46 acts as insulation to prevent accidental electric shock.

[0032] In this invention, an abutment ring 47 is fixedly connected to the end of the rubber telescopic tube 46. A third spring 45 is installed between the abutment ring 47 and the fixing block 52. The third spring 45 is movably sleeved on the outside of the rubber telescopic tube 46. One end of the abutment ring 47 abuts against the main body 1 of the electricity meter, thereby enabling the compressed rubber telescopic tube 46 to extend quickly.

[0033] In this invention, a knob 43 is threadedly connected to the plug 41. The threaded end of the knob 43 abuts against the outer sheath of the wire 2. A rubber tail tube 42 is fixedly connected to the plug 41 at the entry end of the wire 2. The rubber tail tube 42 is movably sleeved on the outside of the wire 2 to reduce bending. The wire 2 moves through the plug 41. The plug 41 and the wire 2 are locked together by the knob 43.

[0034] In this invention, an abutment component 44 is connected to the main body 1 of the electricity meter. The abutment component 44 includes an abutment block 441. The main body 1 of the electricity meter is slidably connected to each plug 41 with an abutment block 441. A second spring 442 is installed between the abutment block 441 and the main body 1 of the electricity meter. The bottom end of the plug 41 is provided with an abutment groove 443. The abutment block 441 extends into the abutment groove 443 through the second spring 442. The abutment groove 443 is arc-shaped, so that when the wire 2 is pulled out, the abutment block 441 can detach from the abutment groove 443, avoiding the wire 2 from being fixed on the main body 1 and being damaged due to strong pulling.

[0035] Working principle: The main body 1 of the electricity meter is a smart electricity meter with a built-in digital switch and battery. After the operator installs the main body 1, they insert a key into the lock cylinder 71, turn the key, and drive the lock tongue 72 to disengage it from the slot 73, releasing the limit on the push block 543. The cover plate 31 is used for protection. During operation, the wire 2 transmits current to the first terminal 56, and then through the conductive cylinder 59 to the second terminal 57, sending the current into the main body 1 of the electricity meter, thereby measuring and controlling the electricity. The current is then sent out from the other second terminals 57, through... The overcurrent sensor 62 detects the current flowing through the conductive cylinder 59 and transmits the electrical signal to the main body 1 of the energy meter through the connecting line 61. The main body 1 of the energy meter processes the electrical signal. Each current input and output terminal is equipped with a current sensor 62, which facilitates precise control of the power. When a short circuit occurs, the current detected by the current sensor 62 increases, and the digital switch built into the main body 1 of the energy meter automatically disconnects, thereby avoiding safety accidents. By comparing the current at the input and output terminals, it can be determined whether there are problems such as electricity theft, leakage, or energy meter malfunction. In the event of a short circuit, the main body 1 of the electricity meter controls the solenoid valve 542 to operate. The solenoid valve 542 opens, and the first airbag 544 is compressed. The gas inside the second airbag 545 passes through the first airbag 544 and is discharged from the exhaust pipe 547. Under the push of the fifth spring 549, the push block 543 slides, pushing the push rod 546. The push rod 546 is shaped like a thumbtack, which facilitates the compression of the second airbag 545. The gas inside the second airbag 545 is discharged, and the second airbag 545 is compressed. The push block 543 drives the slider 55 to slide. Under the action of the connecting block 541, multiple sliders 55 slide synchronously, causing the conductive cylinder 59 to disengage from the second terminal 57, thereby achieving power outage and ensuring power supply. For safety, to prevent electricity theft during use, when the cover 31 is opened by unauthorized personnel, the pressure block 51 disengages from the first airbag 544, the compressed fourth spring 548 extends, causing the first airbag 544 to inflate, and the gas inside the second airbag 545 enters the first airbag 544. At the same time, the limit on the push block 543 is released. Under the push of the fifth spring 549, the push block 543 slides, and the slider 55 slides, thereby cutting off the power. The main body 1 of the electricity meter can send a power-off signal to the personnel, thereby reminding them to disconnect the power without authorization. During use, opening the cover 31 can also realize the function of manually cutting off the power in an emergency, increasing practicality. When the wire 2 is pulled, the wire 2 disengages from the limit of the bolt 53. Under the limit of the knob 43, the wire 2 drives the plug 41 to disengage from the main body 1 of the electricity meter. The contact block 441 slides and disengages from the contact groove 443. The contact ring 47 loses its contact. After the wire 2 is disengaged, the compressed third spring 45 extends, thereby pushing the contact ring 47. The compressed rubber telescopic tube 46 extends, thereby wrapping the end of the wire 2 to prevent accidental contact by personnel and thus increase safety.
